Confusion about RC channels

Hi~
I encountered some confusion while trying to confirm the functionality of RC channels from the documentation. ( RC Input Channel Mapping (RCMAP) — Copter documentation , RC Input (aka Pilot Input) — Dev documentation)
I noticed that only the first 4 channels are defined as corresponding to Roll, Pitch, Throttle, and Yaw. However, for a Rover (specifically a ground vehicle), the concepts of roll/pitch/yaw don’t seem applicable in the traditional sense. From a logical standpoint, only steering and throttle should be functionally relevant. Yet the RC input description still includes these channel assignments, so I’m not sure if my understanding is correct.

Additionally, is the channel for control mode switching different across platforms? For example, the documentation states: “The default flight mode channel is 8 for Plane and Rover and 5 for Copter.” Is this information still accurate?

I wonder what the RC channels[1-8] for Plane and rover correspond to?

wow … I see… :face_with_spiral_eyes:
thanks a lot!
